How long it takes for a bottle?
Baby is consuming daily something like 15% of his weight.
 
At breast, he needs 3 hours and one hour at bottle, but baby is not a sponge…
 
Going faster is what everyone wants, but 15 minutes is really a minimum, baby is sucking, not drinking, this is physiological.
 
If the flow is too strong and if the bottle is quickly finished (less than 10 minutes), baby will regurgitate, being in respiratory apnea with the risk of wrong route and ear infection.
 
He will feel bloated with a good chance to cry…
